Adaptive content delivery

ABSTRACT

A method and apparatus that provides adaptation in the content delivered to a palmtop computer. Connections between a palmtop computer and the Internet can vary from low speed dial-up to very high speed. Also, a palmtop computer&#39;s display, memory and processing power can vary considerably. Communication with the Internet is generally through a proxy server that can deduce these considerations from the palmtop computer&#39;s serial number and/or other information specified by user. The proxy server can then adapt the content based upon these considerations (e.g. only send two bit gray scale images to non-color palmtop computer, only send first frame of animated gif to low processing power palmtop computer, etc.).

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of adaptive content delivery and in particular to adaptive content delivery to a palmtop computer.

2. Background

As the components required to build a computer system have reduced in size, new categories of computer systems have emerged. One of the new categories of computer systems is the “palmtop” computer system. A palmtop computer system is a computer that is small enough to be held in the hand of a user and can be “palm-sized.” Most palmtop computer systems are used to implement various Personal Information Management (PIM) applications such as an address book, a daily organizer and electronic notepads, to name a few.

While these palm sized computers (“palmtop” computers) have dramatically reduced size when compared to a desktop or notebook computer, the user would like to be able to perform many of the same types of functions, such as accessing content on the Internet, performed using physically larger and more powerful computers. The existing infrastructure (e.g., the Internet) has a wealth of content that the users of palmtop computers wish to access, but since this infrastructure was developed for more powerful computers, it is often difficult for users of palmtop computers to readily take advantage of the content available. Moreover, the existing palmtop computers have varying levels of processing power, communication power, display power and other attributes. As this class of computer evolves, such attributes will be ever changing as the technology permits greater power, more memory, and better display capabilities. There is currently no way to adapt the content to the growing power available in palmtop computers.

SUMMARY OF THE INVENTION

Accordingly, what is needed is a system with the ability to adapt to the varying capabilities of palmtop computers and connection methods as they evolve.

A method and apparatus that provides adaptation in the content delivered to a palmtop computer. Connections between a palmtop computer and the Internet can vary from low speed dial-up to very high speed. Also, a palmtop computer's display, memory and processing power can vary considerably. Communication with the Internet is generally through a proxy server that can deduce these considerations in any number of ways. The proxy server can then adapt the content based upon these considerations (e.g. only send two bit gray scale images to non-color palmtop computer; only send first frame of animated gif to low processing power palmtop computer, etc.). This provides an advantage of matching the capabilities of the palmtop computer with the richness of the content delivered to optimize the transmission time and processing power required to enhance the user's experience.

A method of adapting content for transmission to a palmtop computer consistent with an embodiment of the invention includes: receiving an identifier from the palmtop computer; determining a profile for downloading information to the palmtop computer; and adapting content to be transmitted to the palmtop computer based upon the profile.

A method of adapting content for transmission to a palmtop computer consistent with an embodiment of the present invention includes: receiving an identifier from the palmtop computer, the identifier comprising a serial number and a request header transmitted from the palmtop computer; determining a processing power for a processor residing within the palmtop computer by reference to the identifier; determining a display resolution parameter and a display color handling ability for a display of the palmtop computer by reference to the identifier; determining a display parameter for a display of the palmtop computer by reference to the identifier; determining an amount of memory available to the palmtop computer from the identifier; determining a data transmission format; determining a transmission speed for transmission to the palmtop computer; selecting a profile for downloading information to the palmtop computer; and adapting content to be transmitted to the palmtop computer based upon the profile.

A storage medium storing instructions which, when executed on a programmed processor, carry out a process consistent with embodiments of the present invention of adapting content for transmission to a palmtop computer includes: receiving an identifier from the palmtop computer; determining a profile for downloading information to the palmtop computer; and adapting content to be transmitted to the palmtop computer based upon the profile.

The above summaries are intended to illustrate exemplary embodiments of the invention, which will be best understood in conjunction with the detailed description to follow, and are not intended to limit the scope of the appended claims.

System 100 contains a front cover 210 having an outline of region 106 and holes 75 a for receiving buttons 75 b. A flat panel display 105 (both liquid crystal display and touch screen) fits into front cover 210. Any of a number of display technologies can be used, e.g., LCD, FED, plasma, etc., for the flat panel display 105. A battery 215 provides electrical power. A contrast adjustment (potentiometer) 220 is also shown. On/off button 95 is shown along with an infrared emitter and detector device 64. A flex circuit 230 is shown along with a PC board 225 containing electronics and logic (e.g., memory, communication bus, processor, etc.) for implementing computer system functionality. The digitizer pad is also included in PC board 225. A midframe 235 is shown along with stylus 80. Position adjustable antenna 85 is shown.

A radio receiver/transmitter device 240 is also shown between the midframe and the rear cover 245 of FIG. 3. The receiver/transmitter device 240 is coupled to the antenna 85 and also coupled to communicate with the PC board 225. In one implementation the Mobitex wireless communication system is used to provide two way communication between system 100 and other networked computers and/or the Internet via a proxy server.

FIG. 4 is a perspective illustration of one embodiment of the cradle 60 for receiving the palmtop computer system 100. Cradle 60 contains a mechanical and electrical interface 260 for interfacing with serial connection 108 (FIG. 2B) of computer system 100 when system 100 is slid into the cradle 60 in an upright position. Once inserted, button 270 can be pressed to initiate two way communication between system 100 and other computer systems coupled to serial communication 265.

Referring now to FIG. 6, a plurality of Palmtop Computers are illustrated interacting with a wireless or wired data network. In this figure, palmtop computer 602 having color display 608 communicates via its antenna with one of a plurality of base stations 614 comprising a network of such base stations of a wireless/Internet service provider. Each of the base stations 614 is connected to a data center 620, either directly or via the Internet 52. In addition, data center 620 is connected to the Internet 52 which places all of the capabilities of the Internet and the World Wide Web at the disposal of the data center 620.

The data center 620 can provide a number of services to palmtop computers including a service called “Web clipping” via a Web clipping proxy server within the data center 620. “Web clipping” is a process by which a palmtop computer can effectively provide Internet services to the user within its environment of limited communication bandwidth, limited memory, limited display and limited processing capabilities. The concept of Web clipping is based on a principal of minimizing the amount of information that is communicated to and from palmtop computer. That is, the less data transferred the more efficient the communication system. The query is then submitted to the data center 620 in the form of a very small message (typically less than 50 bytes).

The data center 620 serves as an interface to the internet 52 which pulls the desired information from the internet and returns a response to the palmtop computer in a response which is typically less than 500 bytes compressed. As a result, the user is able to quickly obtain the information desired from a particular Web page and display Web pages on the varying resolution display of palmtop computers. Web clipping is described in greater detail in U.S. patent application Ser. No. 09/087,515 Filed May 29, 1998 entitled “Method and Apparatus for Communicating Information Over Low Bandwidth Communications Network”, naming Hawkins et al. This application is hereby incorporated by reference.

This approach has the benefits of providing near instant access to the Internet while simultaneously providing low cost of service by controlling the airtime usage. This in turn results in long battery life since transmissions from palmtop computer may be a substantial drain on batteries.

The Web clipping proxy server in data center 620 is responsible for converting standard Internet protocols and content from a Web page into a form that is tuned for transmission across a wireless network and for display on a very thin client device such as a palmtop computer. The Web clipping proxy server uses standard Internet and security protocols (TCP, HTTP and SSL) to HTML servers to insure compatibility. However, on the wireless side, it adjusts everything to support extremely low bandwidth and latency. Moreover, the Web clipping proxy server compresses the data from the Internet to insure maximum transmission efficiency in the wireless environment. Data center 620 having Web clipping proxy server is currently implemented for the commercially available Palm VII wireless palmtop computer system as a service called Palm.net™ operated by Palm Computing, Inc.

Web clipping has been found to be a very effective method for providing Internet content to users of palmtop computers. However, as the abilities of such palmtop computers evolve, their ability to deal with more complex content needs to be addressed so that the user can enjoy a richer experience with using content from the Internet 52 or other sources. In the example shown in FIG. 6, palmtop computer 602 has the ability to communicate at 9600BPS via its wireless communication capabilities and has a color display However, consider palmtop computer 618 also having a color display 624 and a high speed 4 MBPS infrared connection to the Internet 52 through LAN hub 622. Obviously, this palmtop computer could potentially receive data at a much higher rate and, providing palmtop computer 618 has the available processing power, memory, etc., it could deal with a greater inflow of information without annoying the user with unnecessary delays than that of palmtop computer 602.

Palmtop computer 630 includes a monochrome display 634 and is connected at a higher communication rate of 19.2 KBPS through cellular telephone 640 than the communication rate of palmtop computer 602, but at a lower rate than that of palmtop computer 618. Depending upon the processing power of the palmtop computers' internal CPU, the amount of memory, connection speed, display type, display resolution, connection speed, etc., it would be desirable to adapt the content delivered to the palmtop computer to obtain a good compromise of performance speed versus richness of content.

Referring now to FIG. 7, a high level flow chart of a process 700 illustrates an embodiment consistent with the present invention to provide adaptive content delivery starting at 702, At 706, an identifier is received by the proxy server at data center 620. In the preferred embodiment, this identifier may include the serial number of the palmtop computer itself. In other embodiments, a header may be transmitted as the identifier or in addition to the identifier, with the header including information such as an amount of RAM memory in the palmtop computer or other relevant parameters. In other embodiments, the header may simply designate a class of palmtop computer that identifies the general capabilities of the palmtop computer. Many variations of such identifiers can be devised by those skilled in the art.

The palmtop computer's abilities are looked up in a database at 710 by the identifier (or header information) so that the palmtop computer's characteristics can be determined, The palmtop computer's capabilities can be determined in any number of ways (e.g. by serial number, model number, device type, etc. as shown in TABLE 3). Such data can be automatically delivered in a web clipping request packet and used as a key to the database at 701. Connection speed can be stored in the database, but is preferably determined dynamically, for example, by measuring round trip time for a so-called “ping” request or querying the wireless network provider. If the palmtop computer is manufactured by a provider of services to the data center 620, the serial number or other identifier can be used to look up relevant information needed to determine the capabilities of the palmtop computer. Otherwise, the header information can be formatted to contain all needed information. At 714, once the data center knows the abilities of the palmtop computer, the content can be adapted to the abilities of the palmtop computer during the ensuing communication session at 718 by conforming the adaptation process to a particular profile suitable to the palmtop computer at hand. The process ends at 724 when the communication session is terminated.

The adaptation process of 714 can take many forms depending on the nature of the capabilities of the palmtop computer. Thus, the exemplary embodiments described as follow are merely intended to be illustrative of the principles of the present invention and not limiting to the scope of the invention. Consider, for example, a palmtop computer having comparatively low processing power, connected by a low speed connection, having a monochrome low resolution display. Such a palmtop computer might be consistent with a first generation of palmtop computers which are currently still widely in use. In general, it is desirable to minimize the amount of data communicated with such palmtop computers due to their limited processing power, display capabilities and connection speed. Thus, for example, Internet content with high resolution, rich colors (e.g., 32 bit color resolution) and animated GIF icons would be annoying to the user due to the large download time. Moreover, receiving and processing such content could rapidly drain the batteries of such a palmtop computer. Accordingly, it is advantageous that the content be matched to the palmtop computer's abilities. Thus, such content can be processed by converting color images to lower resolution two bit gray scale images that require less data and processing power to generate. Additionally, animated GIF icons can be truncated so that only the first frame of the icon is transmitted to eliminate the animation but give the user a usable icon, further reducing the amount of data and processing power required.

As described above, this can be accomplished by reference to information stored in a table such as TABLE 1 below in the data center 620. Many variations in the content of TABLE 1 are possible without departing from the invention. In this exemplary case, the palmtop computer of interest might correspond to serial number 123456. The connect speed shown and data format (e.g., Mobitex or CDMA), can be deduced from the incoming communication from the palmtop computer or can be a registered parameter. It is noted that for this exemplary embodiment, the various attributes of the palmtop computers may be classified coarsely as shown (e.g., low and high, monochrome and color). Such coarse designations may be adequate to determine how to adapt the content, however, this is not to be limiting since these attributes can be more exactly defined (e.g. processing power in MIPS, etc., connection speed in KBPS, etc.) without departing from the invention.

TABLE 1 Serial Display Display CPU Connect Speed (may be Number Type Resolution Power dynamically deduced) 123456 Monochrome Low Low Low 234567 Color Low Low Low 345678 Monochrome Low Low Low 456789 Monochrome High High Low 567890 Color High High High

In the example above, the content is adapted according to parameters designed to suit the palmtop computer of interest. In TABLE 2 below, the parameters used for transmitting content to the palmtop computer is illustrated. Thus, TABLE 2 is used to determine an appropriate profile for carrying out the adaptation.

TABLE 2 Animated Audio Sample Display Serial Number GIF Color rate Resolution 123456 First frame  2 bit grey Low Low 234567 First frame  8 bit color Low Low 345678 First frame  2 bit grey Low Low 456789 First frame  4 bit grey High High 567890 Yes 16 bit color High High

Now consider palmtop computer serial number 567890. This palmtop computer has substantially greater capabilities than that previously described. In this case, animated GIF icons and other images can be handled by the higher processing power of the CPU. Moreover, higher resolution color images (that take large amounts of data to describe) can be handled reasonably as 16 bit color images with higher resolution due to the higher processing power, richer display and higher connect speed.

In an alternative to the examples given above, a set of classes of palmtop computers can be established so that the identifier transmitted by the palmtop computer might need to only be a designation of class. In this case, the class designation can carry with it all of the information necessary to carry out the appropriate adaptation by reference to a table such as TABLE 3 below to determine an appropriate profile for carrying out the adaptation. In still other embodiments, each relevant parameter can be transmitted as the identifier in the header to the proxy server without departing from the invention. It will be clear to those skilled in the art that the required information can be formatted to use a minimal amount of data so that the overhead required to implement the present invention is minimized.

TABLE 3 Palmtop Animated Audio Sample Display Class GIF Color rate Resolution 01 First frame  2 bit grey None Low 02 First frame  8 bit color Low Low . . . . . . . . . . . . . . . 99 Yes 32 bit color High High

As previously described, the examples above are considered only as illustrative of the concept of the present invention. Optimization of the various parameters is needed to achieve the best compromise between processing and download time on one side and richness of content on the other. While this example uses only coarse measurements (e.g., high and low), the present invention contemplates use of more exact parameters. Moreover, many such parameters may be handled to optimize the present invention including memory, screen size, compression level, audio and video abilities, etc. It is contemplated that the present invention will be carried out using a programmed processor residing on the proxy server within the data center 620 Accordingly, the program instructions for carrying out the processes of the invention can be stored on any suitable electronic storage medium for processing on such server.

Those skilled in the art will recognize that the present invention has been described in terms of exemplary embodiments based upon use of a programmed processor. However, the invention should not be so limited, since the present invention could be implemented using hardware component equivalents such as special purpose hardware and/or dedicated processors which are equivalents to the invention as described and claimed. Similarly, general purpose computers, microprocessor based computers, micro-controllers, optical computers, analog computers, dedicated processors and/or dedicated hard wired logic may be used to construct alternative equivalent embodiments of the present invention.

Those skilled in the art will also appreciate that the embodiments described above can be implemented using disc storage as well as other forms of storage including Read Only Memory (ROM) devices, Random Access Memory (RAM) devices; optical storage elements, magnetic storage elements, magneto-optical storage elements, flash memory, core memory and/or other equivalent storage technologies without departing from the present invention. Such alternative storage devices should be considered equivalents.

The present invention is preferably implemented using a programmed processor executing programming instructions that are broadly described above in flow chart form and can be stored on any suitable electronic storage medium. However, those skilled in the art will appreciate that the processes described above can be implemented in any number of variations and in many suitable programming languages without departing from the present invention. For example, the order of certain operations carried out can often be varied, and additional operations can be added without departing from the invention. Error trapping can be added and/or enhanced and variations can be made in user interface and information presentation without departing from the present invention. Such variations are contemplated and considered equivalent.

While the invention has been described in conjunction with specific embodiments, it is evident that many alternatives, modifications, permutations and variations will become apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended that the present invention embrace all such alternatives, modifications and variations as fall within the scope of the appended claims.
